Great products that do exactly what is promised.

I have used this product in 3 different vehicles plus a lawnmower and generator. I have not noticed an increase in fuel economy but all the vehicles are fairly new. I have noticed that the engines run and idle very smoothly and that none of them burn oil between changes. If my engines are still running at 200,000 miles I know that this is everything them. For now I believe it is reducing wear and is keeping this running smooth.

This is my second purchase and I'm using this product now. It does everything they say, smoother cooler engine, stronger and better gas mileage. Wouldn't do without this product again.

Great product and value
